I have to agree with the post above. An RM750x would be a better choice.Hi, is a 650w Plus Gold enough for a 3070 ti and a 5600x CPU? Thanks. PSU Model: Corsair TX650M
Nvidia recommends a 750 watt PSU with a 3070 Ti.
I used to own a TX650m myself, and I used it with my overclocked RTX 2080, which drew as much as 265 watts (only 25 watts less than a 3070 Ti is rated to draw). So you'll probably be all right for the time being, but running any PSU at the limit of what it can provide will eventually wear it out, and when it does, it may damage the hardware it is connected to. So I would recommend that you upgrade your PSU to a Corsair RM750x or even a RM850x.
